Description

  The present invention relates to a support device for a roof-mounted device used when, for example, a device such as a solar cell module is mounted on a tiled roof.

  When a device such as a solar cell module is mounted on a tiled roof, it is necessary to provide a support device for supporting the device on the roof. Therefore, as a first conventional example, the upper surface of the tile itself is used. There has been proposed a structure in which an upward U-shaped support portion for directly supporting a device base is provided (see, for example, Patent Document 1).

  However, the structure in which the support part is formed integrally with the roof tile has the inconvenience that a tile with a support section has to be manufactured for each tile, and the roof tile itself receives the load of the equipment. It cannot be built and the roof tiles must be made of aluminum die cast or cast iron.

  The above-mentioned aluminum die cast has a problem that the die cost for manufacturing and the unit price at the time of mass production become very high.

  Moreover, cast iron becomes very heavy and has a problem that it cannot be placed on the roof of a typical detached house.

  As a second conventional example of a supporting device that can be used for a general ceramic tile without using a metal tile as in the first conventional example, a through hole is provided in the tile, A support device has been proposed in which a support bolt fixed to a roof structure is protruded from the through hole to the upper surface of the tile, and a device base is fixed to the support bolt (see, for example, Patent Document 2).

  By the way, since the support device of the second conventional example fixes the gantry with support bolts whose position is determined by being fixed to the roof structure, a long hole for fine adjustment of the gantry position is provided in the gantry, or the support is supported. Not only is it necessary to drill the bolt insertion holes on-site, but the support bolts penetrate from the top of the gantry to the back of the roof tile, so rainwater travels through the support bolt to the back of the roof tile. There is a problem that it causes a rain leak.

  Furthermore, since the distance from the force point received by the gantry fixing part of the device to the fulcrum and the action point (the base plate fixed to the base plate) becomes long, the support bolt slides down toward the eaves of the roof. When a load is applied, there is a problem that the support bolt of the thin shaft is easily bent.

  The third conventional support device proposed in order to solve the problem in the second conventional support device uses a roof tile that has a rising peripheral wall around the upper surface of the through-hole and uses a roof tile. A support member formed in a letter shape is placed on the roof base structure so as to fit in the through hole, a waterproof cover member covering the support member through hole is stacked, and a rail-like device fixing member is placed on the cover member Is fixed by screwing a fixing screw through which the cover member and the support member are penetrated from the device fixing member into the roof base structure (for example, see Patent Document 3).

  The support device of the third conventional example has a structure for improving the stability in which the constituent members of the support device are separated from the top surface and the back surface of the roof tile, and rainwater travels around the back surface of the roof tile through the support device. In addition, there is an advantage that rain water applied to the device fixing member is prevented from collecting in the recessed portion of the device fixing member by preventing the cause of rain leakage due to the fact that the support member and the device fixing member have a U-shaped cross section downward. .

JP 09-324498 A Utility Model Registration No. 3084621 Japanese Patent No. 4112405

  However, in the support device of the third conventional example, the fixing member is screwed and fixed in a series from the upper surface of the device fixing member to the roof base structure by forming the supporting member and the device fixing member in a U-shaped cross section downward. When a component of the support device deteriorates after several years after construction, a gap is created between the component and the fixing screw that penetrates the component, and rainwater enters the back side of the roof tile through the fixing screw. There is a problem of causing rain leaks.

  In addition, since the device fixing member is also formed in a U-shaped cross-section, the position of the device mount fixing bolt to the device fixing member is fixed before the device fixing member is attached to the waterproof cover member and the support member. There is a problem that it is very difficult to fine-tune the final frame.

  Furthermore, since the fixing of the equipment fixing member and the fixing of the support member to the roof base structure are performed using the same fixing screw, when force is applied to the equipment fixing member, the fixing screw is against the roof base structure. A load is applied, and asphalt roofing generally stuck to the surface of the roof base structure is broken, and there is a problem that the waterproof performance of the roof is impaired.

  In addition, if the mounting position of the device fixing member is wrong, the fixing screw will be pulled out and the position of the device fixing member will be changed, but once the fixing screw is pulled out, Since the screw hole is opened in the roof base structure and causes rain leakage, there is a problem that the installer needs a great deal of nerve and labor when positioning the device fixing member.

  By the way, the fixing screw provided on the device fixing member is a long hole, and if the fixing screw is loosened, it has a structure that allows fine adjustment of the device fixing member. Once the fixing screw is loosened, the screw insertion hole for the roof base structure is expanded, and the waterproof property of the roof base structure is completely lost.

  Accordingly, an object of the present invention is a support device composed of a plurality of constituent members for attaching a device to a tiled roof made of earthenware, in which fixing to the roof base structure and fixing to each other are separated, and a series of An object of the present invention is to provide a support device for on-roof equipment that can prevent the deterioration of waterproof performance caused by fixing using a fixing screw and can easily adjust the position of an equipment fixing member.

In order to solve the above-described problems, the present invention provides a support block fixed on a roof base material by screwing a lower fixing screw, and a through hole provided in the roof tile so as to overlap the upper surface of the support block. and the cover member in close contact with the peripheral wall to cover the upper opening entire rising peripheral wall of which are disposed so as to overlap the upper surface of the cover member, and the bonding member by screwing the upper fixing screw is secured to the support block together with the cover member The screw shaft for connecting the mount of the equipment mounted on the roof is erected on the upper surface, and the connecting member is fixed to the joining member.

The joining member is provided with an engagement groove on the upper surface of the base plate, the engagement groove is located on the base plate, and an opening located above the groove portion and having a width smaller than the width of the groove portion. The joint member is placed on the cover member in an arrangement in which the length direction of the engagement groove intersects or is parallel to the flow direction of the roof surface. The overlapping portion is fixed to the support block by using an upper fixing screw, and the connection fitting includes an engaging portion that is inserted into the engaging groove of the joining member, and a screw shaft that is provided to stand on the engaging portion. It can be made to attach by engaging an engaging part with respect to the engaging groove.

The support block uses a foamable resin as a material, and has a planar size that fits in a through hole provided in the roof tile and a height that matches or rises to the upper end of the rising peripheral wall of the through hole. And a fixing portion by a lower fixing screw is provided at a lower position with respect to the upper surface, and the entire lower surface can be formed to be a flat plane.

  The cover member is provided so that a peripheral wall projecting to the lower surface side is provided on the periphery of the top plate using a metal plate, and the rising peripheral wall of the through hole provided in the roof tile can be covered from above, A structure in which a plurality of insertion holes for the upper fixing screw are provided may be employed.

Here, the support block is fixed to the roof base structure by a lower fixing screw screwed into the fixing portion, and the head of the lower fixing screw is placed on the roof base material in a state where the head fits from the upper surface of the support block. The cover member and the joining member are fixed on the support block with an upper fixing screw, and the upper fixing screw is set to a length that does not reach the roof base material when screwed into the support block. with those, to separate the head exposed surface of the lower fixing screw and the upper fixing screw on the top and bottom of the cover member, as in the case of using the fixing screws of a series, fixed Rain can infiltrate from the surface of the cover member through the screw to the back of the tile or the back of the roof base structure, thereby eliminating the occurrence of rain leakage and the material being polystyrene. The use of the expandable resin, the support block is welded to the surface of the fixing screws, thus improving waterproof performance of threaded portion of the fixing screw with frictional heat generated during screwing of the fixing screws.

  Further, in the upper fixing screw, chips of the support block generated at the time of screwing are filled in the insertion hole of the joining member, and the space of the insertion hole is filled by melting by the frictional heat, so that the waterproof property is improved.

The support block is also a real While inside clogged rather good either hollow, upper fixing screw for fixing the cover member and the joining member, never falls support block reaches roof bed material structure length Is set to

  According to the present invention, the support block is fixed to the roof base structure with the lower fixing screw, and the cover member and the joining member are fixed to the support block with the upper fixing screw in a state of being overlaid on the support block. By separating the screw from the top and bottom of the cover member, it is possible to reliably prevent the generation of rainwater that travels through the fixing screw and enters the back of the roof tile or the back of the roof foundation structure. Can be prevented.

  In addition, since the connection fitting is hooked to the engagement groove of the joining member by using the engaging portion provided on the connection fitting, a punching action is not required for fixing the connection fitting to the joining member, and the waterproof property is improved. In addition to not being damaged, the position of the connection fitting can be adjusted along the engagement groove of the joining member even after the joining member is fixed, and the pedestal fixing work of the apparatus can be performed smoothly, and the work efficiency can be improved.
